* configure.ac: Set LT version to C6/A6/R0.

Signed-off-by: Werner Koch <wk@gnupg.org>

* src/assuan-socket.c (cygwin_fdtable, cygwin_fdtable_cs): New.
(is_cygwin_fd, insert_cygwin_fd, delete_cygwin_fd): New.
(assuan_sock_init) [W32]: Init the CS.
(assuan_sock_deinit) [W32]: Deinit the CS.
(read_port_and_nonce): Add arg cygwin and detect Cygwin socket files.
(_assuan_sock_set_flag): Add "cygwin" flag.
(_assuan_sock_get_flag): Ditto.
(do_readn, do_writen): New.
(_assuan_sock_bind): Create a Cygwin socket file depending on a socket
flag.

--

This code has not been tested.

* src/assuan-inquire.c (assuan_inquire): Clear return args on error.
Read up remaining lines after MAXLEN has been hit.
--

If we would stop immediately at MAXLEN, as we did, the client would
continue to send data which the server may consider as new Assuan
commands.

* configure.ac (BUILD_TIMESTAMP): Set to "<none>" by default.
--

This is based on
libgpg-error commit d620005fd1a655d591fccb44639e22ea445e4554
but changed to be disabled by default.  Check there for some
background.

* src/assuan-defs.h (wipememory2, wipememory): New.  Taken from GnuPG.
* src/assuan.c (assuan_release): Wipe the context.
--

The assuan context has buffers which may carry senitive information.
These buffers could be wiped out with each flush but that is too
expensive.  Thus we only wipe them when freeing the context.

* src/assuan-socket.c (_assuan_sock_set_flag): New.
(assuan_sock_set_flag): New.
(_assuan_sock_get_flag, assuan_sock_get_flag): New.
* src/assuan.h.in (assuan_sock_set_flag): New.
(assuan_sock_get_flag): New.
* src/libassuan.def: Add them.
* src/libassuan.vers: Add them.
--

These new functions are intended for a Cygwin socket emulation.  This
commit merely introduces a generic framework.

* src/assuan-defs.h (_assuan_error): Use error source Assuan if no CTX
is given.

Signed-off-by: Werner Koch <wk@gnupg.org>

* src/assuan-buffer.c (assuan_sendfd): Check that CTX is not NULL.
(assuan_receivefd): Ditto.
--

This change is to align the behaviour with that of assuan_send_data.

* doc/assuan.texi (assuan_inquire): Fix and improve description of
this function.

Upstream version 2.2.1

--

* doc/assuan.texi: fix documentation

--

Reading up on assuan to create python bindings uncovered a few bugs in
the documentation.

Upstream version 2.2.0

debian/patches/0001-Use-the-debian-changelog-timestamp-for-BUILD_TIMESTA.patch: Patch to use the debian/changelog date for BUILD_TIMESTAMP to make build reproducible.

* src/Makefile.am (extra_ltoptions): New.
(libassuan_la_LDFLAGS): Use it.
--

Since gcc 4.8 there is a regression in that plain C programs may link
to libgcc_s.a which has a dependency on libgcc_s_sjlj.dll.  This is
for example triggered by using long long arithmetic on a 32 bit
Windows (e.g symbol __udivdi3).

This patch does not change anything right now but we add it anyway
in case long long will ever be used.

* configure.ac (AM_INIT_AUTOMAKE): Add serial-tests.
* src/Makefile.am (INCLUDES): Rename to AM_CPPFLAGS and remove the
nonexistent ../include/.

* src/assuan-socket-connect.c (assuan_socket_connect_fd): Map fd to
assuan_fd_t.
--

This function is actually not used by GnuPG.  The function should have
taken an assuan_fd but given that it did not we use our usual mapping
from Windows libc fds to an assuan fd.

* src/debug.h: Remove traling ", 0" expression part where not useful.
--

gcc 4.9 detected this.  Probably taken from gpgme but used
differently.
